Module C: Formula & Methodology
The calculator uses the official income tax slabs and rules for FY 2017-18 as prescribed by the Income Tax Department of India. Here’s the detailed calculation methodology:
Step 1: Determine Taxable Income
Formula: Taxable Income = (Gross Total Income) – (Deductions under Chapter VI-A)
Where Chapter VI-A includes:
- Section 80C: ₹1,50,000 max (Investments in PPF, ELSS, NSC, etc.)
- Section 80D: ₹25,000 (₹30,000 for seniors) for medical insurance
- Section 80G: Donations to approved charitable institutions
- Section 80E: Interest on education loan
- Section 24: ₹2,00,000 max for home loan interest
Step 2: Apply Appropriate Tax Slabs
| Age Group | Income Range | Tax Rate | Basic Exemption Limit |
|---|---|---|---|
| Below 60 years | Up to ₹2,50,000 | Nil | ₹2,50,000 |
| Below 60 years | ₹2,50,001 to ₹5,00,000 | 5% | ₹2,50,000 |
| Below 60 years | ₹5,00,001 to ₹10,00,000 | 20% | ₹2,50,000 |
| Below 60 years | Above ₹10,00,000 | 30% | ₹2,50,000 |
| 60-80 years (Senior) | Up to ₹3,00,000 | Nil | ₹3,00,000 |
| Above 80 years (Super Senior) | Up to ₹5,00,000 | Nil | ₹5,00,000 |
Step 3: Calculate Tax Payable
The tax is calculated progressively on different income slabs. For example, for an individual below 60 with ₹8,00,000 income:
- First ₹2,50,000: Nil
- Next ₹2,50,000 (₹2,50,001-₹5,00,000): 5% = ₹12,500
- Remaining ₹3,00,000 (₹5,00,001-₹8,00,000): 20% = ₹60,000
- Total tax before cess: ₹72,500
Step 4: Add Education Cess
3% education cess is added to the calculated tax amount.
Step 5: Apply Rebate under Section 87A
For individuals with total income ≤ ₹5,00,000, rebate of 100% of tax or ₹2,500 (whichever is lower) is available.
Step 6: Calculate Net Tax Payable
Final Formula: Net Tax = (Tax + Cess) – Rebate

Module G: Interactive FAQ
What is the last date for filing ITR for AY 2018-19? +
The original due date for filing Income Tax Returns for AY 2018-19 (FY 2017-18) was July 31, 2018 for most taxpayers. However, the government extended it to August 31, 2018 for all taxpayers except those requiring audit.
For taxpayers requiring audit (businesses, professionals with turnover > ₹1 crore), the due date was September 30, 2018.
Note: Late filing attracts a penalty of ₹5,000 if filed by December 31, and ₹10,000 if filed after that (though reduced to ₹1,000 for small taxpayers with income ≤ ₹5 lakhs).
How is income from house property calculated for tax purposes? +
Income from house property is calculated as follows:
- Determine Gross Annual Value (GAV): Higher of expected rent or actual rent received (with some exceptions)
- Deduct Municipal Taxes: Property taxes paid during the year
- Deduct Standard Deduction: 30% of Net Annual Value (NAV)
- Deduct Home Loan Interest: Up to ₹2,00,000 under Section 24
- Result: Net income from house property (could be negative)
Example: If you receive ₹3,00,000 rent, pay ₹30,000 municipal tax, and have ₹2,00,000 home loan interest:
- GAV: ₹3,00,000
- Less Municipal Tax: ₹30,000 → NAV = ₹2,70,000
- Standard Deduction (30%): ₹81,000
- Interest Deduction: ₹2,00,000
- Net Income: ₹2,70,000 – ₹81,000 – ₹2,00,000 = ₹-11,000 (loss)
This loss can be set off against other income heads.
What are the changes in tax slabs from 2016-17 to 2017-18? +
The most significant change in tax slabs for 2017-18 was the reduction in tax rate for the ₹2.5L-₹5L income slab from 10% to 5%. Here’s a complete comparison:
| Income Range | 2016-17 Rate | 2017-18 Rate |
|---|---|---|
| Up to ₹2,50,000 | Nil | Nil |
| ₹2,50,001 to ₹5,00,000 | 10% | 5% |
| ₹5,00,001 to ₹10,00,000 | 20% | 20% |
| Above ₹10,00,000 | 30% | 30% |
Other changes included:
- Reduction in rebate under Section 87A from ₹5,000 to ₹2,500
- Introduction of 10% surcharge for income between ₹50 lakh to ₹1 crore

Can I file a revised return if I made a mistake in my original filing? +
Yes, you can file a revised return under Section 139(5) if you discover any errors or omissions in your originally filed return. Key points:
- Time Limit: Can be filed anytime before the end of the relevant assessment year (March 31, 2019 for AY 2018-19) or before completion of assessment, whichever is earlier
- Process: File using the same ITR form as original return, but mark it as “Revised Return”
- Requirements: Must have acknowledgment number of original return
- Limitations: Can only revise once (though practically multiple revisions are allowed)
- Consequences: Original return is treated as if it was never filed
Common reasons for revision:
- Missed reporting some income
- Forgot to claim eligible deductions
- Incorrect bank account details
- Mismatch in TDS claims
- Wrong assessment year selected
How is capital gains tax calculated for property sold in FY 2017-18? +
Capital gains from property are calculated differently based on the holding period:
1. Short-Term Capital Gains (STCG)
Holding Period: ≤ 24 months (reduced from 36 months in Budget 2017)
Tax Rate: Added to your income and taxed at your slab rate
Calculation: Sale Price – (Cost of Acquisition + Improvement Cost + Transfer Expenses)
2. Long-Term Capital Gains (LTCG)
Holding Period: > 24 months
Tax Rate: 20% with indexation benefit
Calculation:
- Indexed Cost of Acquisition = Original Cost × (CII of sale year/CII of purchase year)
- Indexed Cost of Improvement = Improvement Cost × (CII of sale year/CII of improvement year)
- LTCG = Sale Price – (Indexed Cost of Acquisition + Indexed Cost of Improvement + Transfer Expenses)
CII for FY 2017-18: 272 (Base year 2001-02 = 100)
Exemptions Available:
- Section 54: Reinvest in residential property (₹2 crore max for urban, ₹1 crore for rural)
- Section 54EC: Invest in specified bonds (₹50 lakh max, 5 year lock-in)
- Section 54F: For non-property assets (full exemption if entire sale proceeds reinvested)
Example: Property bought in 2005-06 (CII: 117) for ₹20L, sold in 2017-18 (CII: 272) for ₹80L:
- Indexed Cost = ₹20L × (272/117) = ₹46.67L
- LTCG = ₹80L – ₹46.67L = ₹33.33L
- Tax = 20% of ₹33.33L = ₹6.67L
What documents should I keep for income tax purposes? +
